These are tutorials someone might want to reference while following this tutorial to tweak their scenes to their preferences.
In terms of rendering realistic grass with animation...I followed the tutorial from 3Dlessons and then referenced the tutorial posted above. I adjusted the turbulence and turbulence freq in the channel box under inputs. And under Flow Animation, I tweaked the Flow Speed but left the 'Texture Flow" selected because I don't want my grass to appear to be growing. I simply want to animate it.
If anyone has experimented with this lesson, I'd love some insight! :D
